To all whom it may concern.- Be it known that I, SAMSON FOX, of Leeds, England, have invented a new and useful Improvement "in Pressed Steel Beams, of

which thefollowing is a full, true, and exact description, reference being had to the acco'mpanying drawings.

This invention relates to a new channelbeam having a closed end of 'a'peeular form. This beam is applicable for structural purposes in architecture, for the frames of vehicles, and generally for the purposes for which channel-beamsare employed; and it consists of a beam having-a solid bent and forged closed end formed from the open-ended beam itself. 7 I

My invention will be readily understood from the accompanying drawings, which represent the different'shapes taken by the beam-- in the process of lnanufacture.

Figure 1 is an end view of an ordinary channel-beam; Fig. 2, a longitudinal view thereof. This beam is placed upon a suitable mandrel in such position as that the downwardly-bent portion is longer than the distance from. the backto the edge'of the beani 'and'i-n the process of manufacturewhichl prefer the end is forceddown atfirst. into the position shown in Figs. 3 and 4, Fig. 3 being a section thiough Fig. .4 on the line in m. Finally, rectangular dies reduce 'it'to being a section through Fig. 6 on the line y'y.

The bulging portion C of the beam is forced ends formed without weld by pressure from the beam itself, substantially as'described.

2. A channel-beam having closed forged ends in a plane at or substantially at right angles to the back of the beam,'the opening of the end projecting beyond the open edges of the beam, substantially as described.

'In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
